丹参注射液联合抗生素治疗急性盆腔炎疗效观察

目的 评价丹参注射液配合抗生素治疗急性盆腔炎的疗效。方法 100例急性盆腔炎患者随机分成两组，治疗组50例静脉滴注青霉素、甲硝唑同时加用丹参注射液，对照组50例仅使用青霉素与甲硝唑注射液。观察治疗前后临床症状与检查结果的改变。结果 两组治疗后相比：总有效率治疗组94％，对照组为76％，差异有显著性（P〈0．05）。完全缓解率分别为61％和30％，差异有非常显著性（P〈0．01）。治疗组炎性包块明显缩小，与对照组比较差异有非常显著性（P〈0．01）。两组均无明显不良反应发生。结论 丹参注射液配合抗生素治疗急性盆腔炎疗效满意。     

Genotoxicity and antileishmanial activity evaluation of Physalis angulata concentrated ethanolic extract

Antileishmanial in vitro tests, as well as Ames and micronucleus assays were performed with a concentrated ethanolic extract of Physalis angulata (EEPA)ResultsEEPA did not present mutagenic effect in Salmonella typhimurium strains at concentration reaching 3000 μg/plate and did not induce mutagenic effects after two oral administrations with a 24 h interval at a dose level of 2000 mg/kg. EEPA presented antileishmanial activity and presented an IC₅₀ value of 5.35 ± 2.50 μg/mL and 4.50 ± 1.17 μg/mL against Leishmania amazonensis and Leishmania braziliensis promastigotes, respectively. In the cytotoxicity test against macrophages, the EEPA had a LC₅₀ of 6.14 ± 0.59 μg/mL. Importantly, the IC₅₀ against L. amazonensis intracellular amastigotes was 1.23 ± 0.11 μg/mL.ConclusionEEPA extract is non-mutagenic and presented a promising pharmacological effect against Leishmania parasites.     

人工股骨头置换治疗高龄患者股骨转子间骨折髓内钉失效的手术时机选择

目的:分析高龄患者股骨转子间骨折髓内钉失效后行人工股骨头置换术的手术时机选择。方法：2013年7月至2019年9月,采用人工股骨头置换术治疗股骨转子间骨折髓内钉固定失效后的17例高龄患者,根据从确诊内固定失效到行人工股骨头置换术的间隔时间将患者分为早期手术和延期手术两组。其中,早期手术组8例,男5例,女3例;年龄80~89（84.88±2.79）岁;间隔1~7（4.13±1.73） d。延期手术组9例,男4例,女5例;年龄80~89（84.22±3.03）岁;间隔15~30（25.56±4.36） d。比较两组患者手术时间、术中失血量、术后首次下地负重时间、术后住院时间、并发症例数及死亡例数。术后1、12个月采用Harris评分评价髋关节功能。结果：术后患者切口愈合良好,早期手术组泌尿道感染1例;延期手术组中,肌间静脉血栓2例,肺部感染1例,泌尿道感染3例,假体脱位1例。17例患者均获随访,时间12~16（14.76±1.86）个月。两组手术时间、术中失血量、死亡例数比较差异无统计学意义（P>0.05）;两组术后首次下地负重时间、术后住院时间、并发症例数比较,差异有统计学意义（P<0.05）。术后1个月两组患者Harris评分比较,差异有统计学意义（P<0.05）;术后12个月两组患者Harris评分比较,差异无统计学意义（P>0.05）。结论：高龄患者股骨转子间骨折髓内钉固定失效后,早期手术同延期手术相比,其死亡率及最终髋关节功能无明显差异,但早期行人工股骨头置换术能够让患者更早下地负重,缩短住院时间,有效减少并发症率,尽快恢复髋关节功能。     

The add-on effect of dengzhan shengmai capsules on secondary prevention of ischemic stroke: A multicentre,randomised, placebo-controlled clinical trial

ObjectiveThe Dengzhan Shengmai (DZSM) capsule is a commercially available type of Chinese herbal medicine frequently administered to improve neurological impairment after stroke. Its ability to prevent recurrent stroke, however, has not been determined. This study therefore evaluated the ability of DZSM as an add-on to conventional secondary preventive agents to prevent recurrent ischemic stroke.MethodsIn this randomised, double-blind, placebo-controlled trial, conducted at 83 hospitals in Mainland China, 3143 patients in 14–180 days after the initial onset of ischemic stroke, were randomly allocated to the DZSM (0.36 g, twice daily for 12 months) or the placebo group. All patients in both groups received standard secondary preventive medications. The primary outcome was the 1-year incidence of stroke. Between group differences were assessed using the Cox proportional hazards model.ResultsIntent-to-treat analysis showed that 58 (3.8%) participants in the DZSM group and 82 (5.4%) in the placebo group experienced new stroke events (hazard ratio = 0.70, 95% confidence interval = 0.50–0.98, P = 0.036). The type and incidence of adverse events were similar in the DZSM and placebo groups.ConclusionsThe addition of DZSM capsules to standard secondary preventive agents provides additional benefits after the initial onset of ischemic stroke, reducing recurrent stroke without increasing severe adverse events. However, further study is needed to elucidate the role of DZSM on the updated practice of conventional secondary prevention for ischemic stroke.

中风急性期证候与血清CRP的相关性及ROC曲线分析

目的:探讨中风急性期证候与CRP的相关性及其对临床的应用价值。方法:运用散射比浊法测定50例中风急性期(均在发病2周内入院)患者血清C反应蛋白(CRP),并进行受试者工作特征曲线(ROC)分析。结果:中风急性期患者CRP水平与痰证积分有一定的相关性(P<0.05),与证候程度无明显相关性(P>0.05);痰证积分对血清CRP阳性诊断的ROC曲线下面积为0.700(SE:0.076;95%CI:0.550～0.849),其诊断界点为10.5分。结论:痰证积分可以预测中风急性期CRP阳性,有利于卒中的临床治疗,扩大《中风病辨证诊断标准(试行)》(1994)的临床使用范围。     

BMP治疗激素性股骨头坏死的研究进展

激素性股骨头坏死(SANFH)是世界性的难治病,其主要受限于局部坏死骨组织修复作用的不足,最终造成股骨头塌陷而导致肢体的功能障碍。而骨形态发生蛋白(BMP)是具有强烈的诱导骨组织形成作用的局部生长因子之一,能弥补激素性股骨头坏死病理过程中骨组织修复的不足。该文简要介绍当前对BMP的基础研究,重点回顾总结了BMP单独或联合治疗激素性股骨头坏死的方法及其疗效以及优缺点,并对其今后的研究方向进行了展望。
